Today, I was shooting my Detective Special and the rotation of the cylinder got hung up a little during rotation. Figured it to be burned powder binding in between cone and cylinder. Later it did it again. This time I could see the problem. I am doing it constantly right now with snap caps. The latch, when I rest my thumb on it rocks and exposes it's lower corner to the rotation of the cylinder causing the rim of cartridges to hang up on it. I wiggled it, it seems to only move backward not forward when wiggling. What can I do? I checked Jerry Kuhnhausen's book and troubleshooting guide and it doesn't cover this. Idea's. Anything I can do to fix it apart from sending it out?
